Will people who live and work near strong magnetic fields be disturbed? What kind of harm will it bring? Or what kind of symptoms are there?

1865, Maxwell predicted electromagnetic waves in the article "Dynamics of Electromagnetic Fields". In the past 100 years, electromagnetic waves have gradually played an important role in all fields of human life, bringing great convenience and fun to our life and work. Modern people have become increasingly inseparable from electromagnetic waves. Radio broadcasting, television, mobile phones, pagers and even microwave ovens used in daily life are all devices that emit electromagnetic waves. It can be said that modern people live completely in the world of electromagnetic waves.

However, electromagnetic wave is a potential pollution source that people ignore. Caused by various electromagnetic waves

"Electrical pollution" is invisible and inaudible, but it is quietly and increasingly threatening human health.

A Pentagon report in 1976 said: "Over-exposure to microwaves can induce heart disease. Experiments on frogs have proved that radiation with the same frequency as the number of heart beats can lead to cardiac arrest. " So far, the research on microwave has proved that the cumulative effect of long-term exposure to microwave or other electromagnetic fields is unbearable. Therefore, some countries have formulated microwave standards that are allowed in the environment. Among them, the maximum amount stipulated by the former Soviet Union is 0.1MW/cm2; American regulation 10 MW/cm2. Scientists have studied the electric field generated by high-voltage lines for a long time, and found that people who work under high-voltage lines for a long time may cause abnormalities in their blood, cardiovascular system and central nervous system, and some young people will feel sexual dysfunction. Robert burke, a surgeon in New York, USA, put some mice in an electric field for a long time, and found that some mice developed tumors and some mice suffered from pinkeye. All these mice had pathological changes in blood cell count, protein and fat. If people are placed in an electric field with a fixed frequency, it is also found that the blood lipid value has changed. In Germany, thousands of babies die of unknown causes every year. German electrical engineer Igor? Gelter found that most of these deaths occurred near electrified railway lines, radio broadcasting or relay stations and radar or high-voltage lines.

Why do electromagnetic waves affect people's health? It turns out that gas molecules can be ionized into positive and negative ions. Initially, they kept the same proportion in the atmosphere, but various factors can change this proportion. For example, air pollution, metal structures, electrical appliances, motors and other reasons have "swallowed up" a large number of negative ions. Experiments show that negative ions play an important role in human health. If animals are placed in an atmosphere that releases negative ions, they will die within 2-8 days. In addition, oxygen can only exist in red blood cells through negative ions. Therefore, negative ions play a role in the propagation and reproduction of oxygen, viruses and bacteria necessary for our breathing and the electromagnetic level in the human body. The biochemical effect of atmospheric ionization makes people gradually understand that reducing the number of negative ions will have harmful effects on human body. Electromagnetic waves are the biggest enemy of "swallowing" negative ions.

Living Environment: Beware of Six Harms of Electromagnetic Radiation

The Indoor Environmental Monitoring Center of China Interior Decoration Association recently issued an environmental warning: when buying a house, we must pay attention to whether the electromagnetic radiation pollution in the community exceeds the standard. At present, many citizens report that the electromagnetic radiation pollution in their newly-built residential areas is very serious, not only the electrical appliances at home are disturbed and cannot be used normally, but also many people have different degrees of discomfort.

Harm of electromagnetic radiation

With the large-scale urban reconstruction and real estate development, some transmission and transmission centers and high-voltage lines originally built around the city have also begun to be developed and constructed, and the electromagnetic radiation pollution problems in the living environment and indoor environment have followed. What harm does electromagnetic radiation do to human body? According to experts, there are six major hazards.

One of the hazards is that it may be one of the causes of childhood leukemia. Medical research has proved that long-term exposure to high electromagnetic radiation will change blood, lymph and cell protoplasm. According to the research of Italian experts, more than 400 children in this country suffer from leukemia every year. The main reason is that they are too close to high-voltage wires, which leads to serious electromagnetic pollution.

The second hazard can induce cancer and accelerate the proliferation of cancer cells in the human body. Electromagnetic radiation pollution will affect the circulatory system, immunity, reproduction and metabolic functions of human body, and even induce cancer in severe cases, and accelerate the proliferation of cancer cells in human body. According to Swiss research data, the probability of breast cancer among residents with high-voltage lines passing around is 7.4 times that of ordinary people. The results of sampling tests conducted by the Texas Cancer Medical Foundation on some patients suffering from electromagnetic radiation show that the cancer cells of workers working near high-voltage lines grow 24 times faster than those of ordinary people.

The third harm affects the human reproductive system, mainly manifested in the decline of male sperm quality, spontaneous abortion of pregnant women and fetal malformation.

The fourth hazard may lead to mental disability of children. According to the latest survey, among the 20 million children born every year in China, 350,000 are handicapped children, of whom 250,000 are mentally retarded children. Some experts believe that electromagnetic radiation is also one of the influencing factors. According to the World Health Organization, electromagnetic radiation from computers, televisions and mobile phones has adverse effects on the fetus.

The fifth hazard affects people's cardiovascular system, which is manifested as palpitation, insomnia, menstrual disorder in some women, bradycardia, decreased heart effort, irregular sinus heart rate, leukopenia and decreased immune function. If the patient with pacemaker is in an environment with high electromagnetic radiation, it will affect the normal use of pacemaker.

The sixth hazard has a bad effect on human visual system. Because eyes belong to the sensitive organs of human body to electromagnetic radiation, too high electromagnetic radiation pollution will cause vision loss, cataracts and so on. High-dose electromagnetic radiation will also affect and destroy the original biological current and biological magnetic field of human body, making the original electromagnetic field of human body abnormal. It is worth noting that different people or the same person have different tolerance to electromagnetic radiation at different ages, and the elderly, children and pregnant women are sensitive to electromagnetic radiation.

Learn to prevent radiation

There are five kinds of people who should pay special attention to electromagnetic radiation pollution: people who live and work near high-voltage lines, substations, radio stations, TV stations, radar stations and electromagnetic wave transmission towers; Personnel who frequently use electronic instruments, medical equipment and office automation equipment; Workers living in modern electrical automation environment; Patients wearing pacemakers; Pregnant women, children, the elderly and patients living in the above environment. If the electromagnetic radiation pollution in the living environment is relatively high, the public must take corresponding protective measures.

Don't put household appliances too concentrated, so as not to expose yourself to the danger of excessive radiation. Especially some household appliances that are easy to generate electromagnetic waves, such as radios, televisions, computers, refrigerators, etc. , are not suitable for centralized placement in the bedroom.

All kinds of household appliances, office equipment, mobile phones, etc. Try to avoid long-term operation, and try to avoid multiple office and household appliances being activated at the same time. The electromagnetic radiation released at the moment when the mobile phone is connected is the largest. When using, the distance between the head and the antenna of the mobile phone should be as far as possible, and it is best to use a separate earphone and microphone to answer the phone.

Pay attention to the distance between human body and office and household appliances, and keep a safe distance when using all kinds of appliances. The farther away from the electrical appliance, the smaller the electromagnetic wave. For example, the distance between color TV sets and people should be 4 to 5 meters, and the distance between color TV sets and fluorescent tubes should be 2 to 3 meters. After the microwave oven is turned on, it should be at least 1 m away, and pregnant women and children should be as far away from the microwave oven as possible.

If the house is close to high-voltage lines, substations, radio stations, TV stations, radar stations and electromagnetic wave transmission towers, experts must be invited to carry out electromagnetic radiation detection. If it is found that it exceeds the national standard after testing, measures should be taken in time.
